DEVICE FOR MEASURING THE TEMPERATURE IN A FLOW CHANNEL OF THE PRIMARY FLOW OF A BYPASS TURBOJET ENGINE.

摘要

The invention relates to a device for measuring the temperature in a flow channel of the primary flow of a bypass turbojet engine as it enters the compressor, comprising a hollow, sealed structure forming a connecting arm (36b) of an intermediate casing (30), which structure is intended to extend radially through a flow channel of the primary flow (16) and a flow channel of the bypass flow (18) of the turbojet engine. The connecting arm (36b) includes at least one air inlet (44) intended to open into the flow channel of the primary flow as it enters a compressor and at least one air outlet (46) intended to open into an area of the turbojet engine in which the ambient pressure is lower than the pressure in the flow channel of the main primary flow as it enters the compressor. The device also comprises a temperature probe (48), the sensitive part of which is located inside the connecting arm.
